BACKGROUND OF THE INVENTION

The present invention relates generally to the field of wirelesscommunication systems. More specifically, the present invention relatesto providing the multifunction capabilities of wireless communicationand on-demand, mobile capture of video content.

Currently there are more than 169 million wireless subscribers in theUnited States. In previous years, industry experts have predicted thatwireless phone sales were close to or had reached a saturation point.However, in recent years, a multitude of new features have been added tothe basic wireless phone design to entice consumers to make new wirelessphone purchases and sign up for new wireless provider plans. Therefore,wireless phones that provide features such as internet access,photographic capabilities and electronic game interfaces make up asignificant and growing percentage of the overall wireless phone market.Last year about nine million camera equipped wireless phones were soldin the United States. And this year it is expected that another 28million camera equipped wireless phones will be sold in the UnitedStates. Additionally, worldwide 60 million camera wireless phones weresold last year and more than 100 million are expected to be sold thisyear.

Because of the changes in wireless phone technology, consumers todayexpect more features from their wireless phones. These features may befor convenience, e.g., electronic address books and calendars, orleisure, e.g., electronic games and cameras. It is predicted that thenext generation of wireless phones will be a combination of phones,PDAs, digital cameras, and handheld gaming devices. In fact, thanks tothe digital revolution, the feature set of current wireless phones hasincreased to include extras such as games, music players, and textmessaging. Future wireless phones might not look radically differentfrom existing wireless phones, but their integrated abilities likelywill change significantly.

As wireless phone capabilities expand, manufacturers have to look fornew features to capture the attention of wireless phone consumers. Inthe last year the first mobile phones with integrated television tunerswere introduced. These television-wireless phones integrate a televisiontuner and a video decoder to provide the consumer with the ability towatch free over-the-air programming.

However, the existing wireless phone television art has severaldeficiencies with regard to content. While a television tuner providesconsumers with the means to view over-the-air programming, it has thedrawback that it cannot dependably provide on demand content, i.e.,certain over the air channels may not be available during the time theconsumer wishes to view television or the program(s) the consumer wishesto view may not be available at that time. Further, using the wirelessphone purely as a playback device limits the wireless phone users'ability to avail themselves of the mobility and availability of thewireless phone to create as-desired content for later playback.

There are many limitations to viewing television content on a wirelessphone that is merely the combination of a wireless phone and televisiontuner. For instance, a wireless phone is a mobile device carried by anindividual to make wireless telephone calls, as such, a person viewing atelevision program on a wireless phone is likely to be interrupted byincoming calls or may need to make outgoing calls. Additionally, becausea wireless phone is a mobile device it is highly likely that televisionviewing on such a device will occur in public or other locations wherethe wireless phone user may be interrupted during his or her televisionviewing.

As depicted in FIG. 1, thewireless digital video recorder 100 comprises a wireless phone 110 thatis equipped with a display 115 for, among other things, displaying videocontent. The video content may be broadcast by a video content provider120 or derived from some other video content sources. The video contentprovider 120 may be a television broadcaster, an Internet multicaster, asatellite provider, a wireless/cellular network provider, a third-partyassociated with such persons, or the like. The video content may bebroadcast by the video content provider 120 over the air, via satellite,over a network—such as the Internet, a wireless (cell) network—or thelike. Over-the-air video content may be video content which abroadcaster transmits over the air using, for example, a VHF radiotransmitter.

In some embodiments of the present invention, the wireless digital videorecorder 100 is equipped with a receiving module 130. In differentaspects of the present invention, the receiving module 130 may includean antenna—such as an ultra high frequency (“UHF”), very high frequency(“VHF”), or high definition (“HD”) antenna—a wireless fidelity (“WiFi”)receiver, a WiMAX receiver, a satellite receiver, a receiver forreceiving video content from a wireless/cellular network, a receiver forconnecting to a cable television source, a modem for connecting to acomputer network, a broadband connector such as an Ethernet port, or thelike. WiMAX is an implementation of the IEEE 802.16 standard, WiMAX mayprovide metropolitan area network connectivity at speeds of up to 75Mb/sec. In certain aspects of the present invention, the receivingmodule incorporates a booster antenna.

In some embodiments of the present invention, the receiving module 130may feed its output to the tuner 140. In certain aspect of the presentinvention, the tuner 140 may tune the signals available to the receivingmodule 130, amplify the tuned signal and/or convert it into a videosignal, as appropriate. The tuner 140 may be designed for NationalTelevision Standards Committee (NTSC), PAL broadcast, SECAM, DigitalSatellite System (DSS), Digital Broadcast Services (DBS), AdvancedTelevision Standards Committee (“ATSC”), high-definition (“HD”) signals,and/or a combination of these signals, and/or any other availablebroadcast signal. In alternative embodiments, video content may not needto be tuned. For example, the video content may be received from theInternet or from another video content source in a format that need notrequire tuning.

In some embodiments of the present invention, the video signal from thetuner 140 may be decoded and/or digitized by the decoder 150. Thedecoder 150 may be capable of analog to digital conversion, digital todigital conversion, digital to analog to digital conversion, or thelike. In some aspects of the present invention, the decoder 150 mayconvert the video signal from the tuner 140 to a YCbCr 4:2:2 digitalformat. In certain aspects of the present invention where the videocontent is received in the proper format, e.g. from a computer network,such as an Internet Protocol broadcast over the Internet, or is alreadyin digital form, digitizing by the decoder 150 may not be necessary. Incertain aspects, the decoder 150 may be capable of decoding NTSC, PAL,SECAM, DSS, DBS, ATSC, or HD signals, a combination of these signals,and the like, for display on a display screen 115.

In general, decoders produce video signals with 640×480, 720×480, or720×576 pixel formats. As such, in certain aspects of the presentinvention, a screen formatter 160 may be used to scale the video contentdecoded by the decoder 150 for display on the display screen 115 of thewireless digital video recorder 100. In some aspects of the presentinvention, the screen formatter 160 may scale the video content fordisplay on the quarter common intermediate format (“QCIF”), which is 176by 144 pixels. In other emspects, the screen formatter 160 may scale thevideo content for display on the quarter video graphics array (“QVGA”),which is 320 by 240 pixels. Alternative aspects of the present inventionmay provide for scaling of different high definition formats as theyevolve. In other embodiments of the present invention, screen formattingmay not be performed prior to recording of the video content. However,video content that is not formatted prior to recording requires greaterstorage requirements.
